Abstract

La présente invention concerne un réfrigérateur équipé d'un dispositif compresseur (21), d'un échangeur thermique (24) disposé à l'extérieur, d'une soupape de détente (25) à commande électrique disposée à l'extérieur, et d'un échangeur thermique (32) disposé à l'intérieur. Le dispositif compresseur (21) est constitué de deux compresseurs (2a, 2b) raccordés en parallèle, chaque compresseur (2a, 2b) étant pourvu d'un bloc d'évacuation d'huile (40) conçu pour évacuer de l'huile de lubrification lorsque la quantité d'huile de lubrification conservée dans une boîte à huile atteint un niveau déterminé.
